soAP-PREss.

SPECIFICATION forming part of Letters Patent No. 225,287, dated March 9,1880.

Application filed August 28, 1879.

To all whom it may concern Be it known that I, CHARLES L. INGALLS, ofLowell, in the county of Middlesex and Commonwealth of Massachusetts,have invented certain new and useful Improvements in Soap-Presses, ofwhich the following is a specification. i I

My invention consists 1n the liftingrod pivoted to the cross-head, andprovided with a bend and with a hook beveled on its under side, incombination with a shipping-rod, a spring, and a slide provided with astud to lift the pressed bar out of the female die.

In the accompanying drawings, Figure 1 1s a front elevation of asoap-press embodying my invention; Fig. 2, a side elevation ofthe same;Fig. 3, an enlarged view of the liftingrod and shipping-rod, and Fig. 4a cross-see tion of the periphery of the eccentric and strap.

A is a stout frame, supporting at the top a shaft, B, to which, by meansof the pulley C, a rotary motion is communicated, C being a loosepulley. A gear, D, on said shaft B takes into another gear, D, of largerdiameter, on

the shaft B.

To the shaftB are secured the balance-wheel E and the eccentric F. Theeccentric F is provided with an annular ridge, G, on its pc- 0 riphery,which enters a groove, G, cut on the inside of the strap H, which keepsthe strap from getting off from the eccentric. The groove G also servesto retain the oil used for lubricating said strap and eccentric. The

5 strap is provided with an oil-hole, I, which leads into the groove G,and to which an oilcup, J, may be applied. i y The strap is made inhalves secured together by screws K K. Below the eccentric 4.0 is aconnecting-rod, L, rigidly secured to strap H, and having its lower endpivoted at Q to the cross-head Z. The cross-head Z is limited to avertical motion by the upright guide-rods M M, which pass through thecrosshead near 4 5 its ends, and are held in place by brackets N N,attached to the frame A.

Below the cross-head is a punch or maledie, O, secured to saidcross-head by a screw, S, which turns in the cross-head, so that byloosening the check-nut T the punch O can be raised or lowered byturning it around to in crease or diminish its distance from the top ofthe slide O at the bottom of the stroke, according as the bar of soap tobe pressed is intended to be thicker or thinner.

A horizontal table, P, is supported by the frame A, and is slotted at Itto receive the punch O, which fits it. 0 is a vertical slide, the upperend of which enters the slot R, and, with the sides and ends of saidslot, forms a box or female die, in which the soap is pressed by thepunch O. The slide 0 runs through a horizontal rail, A, secured to theframe A.

A stud, U, projects from the back of the slide 0. A lifting-rod, V,provided with a bend, V, and a hook, V, is pivoted at its upper end tothe back of the cross-head Z, and runs in a shipping or hooked rod, W,which prevents the rod V from being drawn too far to the right by thespring X. The hook V on the lower end of said rod V is beveled on itsunder side, so that when the cross-head descends, carrying said rod Vand hook V, the hook will slide past the stud U; but when the rodV isdrawn up said hook will catch the stud and lift the slide 0, whichforces the bar or cake of soap up out of the slot R.

The bend V on the right of the rod V, running in the shipper W, throwsthe hook V to the left and disengages it from the'stud U just as the topof the slide 0 reaches the top of the table P, and the slide 0 thenfalls by its own weight, the bar of soap being removed by an attendantand an unstamped bar being putin its place before the punch O descendsagain.

The top of the slide 0 and the bottom of the punch 0 may be engravedwith such words or figures as it is desired to impress on the soap. 1

In soap-presses heretofore used the soap has been pressed into bars andstamped by a blow.

The advantages of my press are, that it applies a great power verygradually to the soap and squeezes out the surplus moisture of the same,that it will do a great amount of work in a short time, as the attendanthas only to V, and with a hook V, beveled on its under feed the machineand remove the stamped side, the shipping-rod W, the spring X, and 10bars, instead of also running the press by the slide 0, provided withthe stud U, as and muscular exertion, and that the thickness of for thepurpose specified.

5 the bar can be regulated. CHARLES L. INGALLS. I claim as myinvention-- -Witnesses:
